Python for Beginners: How to use a List?

Описание: Does your Python code feel brittle? Are you tired of chasing down IndexError or ValueError bugs in your list manipulations? You're not alone. Welcome to Pumping Python, my name is Jacob Itegboje and in this video, I'm going to give you the exact blueprint to make your code robust and predictable using Test-Driven Development (TDD).

This isn't just another tutorial on Python lists. This is a practical, step-by-step guide on how to think like a test-driven developer. We'll start with a failing test and write just enough code to make it pass—the "Red-Green-Refactor" cycle. This approach forces you to consider edge cases before they become bugs in your application. By the end of this session, you will not just understand list methods; you will have a reliable framework for testing any new component you build.

You will master:
The core philosophy of Test-Driven Development (TDD).
Writing tests for common list methods like .append(), .pop(), and .sort().
How to proactively test for and prevent common exceptions like IndexError and ValueError.
Techniques for testing indexing, slicing, and list manipulation to ensure your code is bulletproof.
